Build and Release / build-and-release (push) Successful in 1m7s
Implements clean structured data collection eliminating all string metric parsing bugs. Collectors now populate AgentData directly with type-safe field access. Key improvements: - Mount points preserved correctly (/ and /boot instead of root/boot) - Tmpfs discovery added to memory collector - Temperature data flows as typed f32 fields - Zero string parsing overhead - Complete removal of MetricCollectionManager bridge - Direct ZMQ transmission of structured JSON All functionality maintained: service tracking, notifications, status evaluation, and multi-host monitoring.
